? ? ? ?this is the ways these sensors are built. There are 'dead' pixels at
both
ends. There is nothing you can do with it.
Stef, can you recommend a SANE compatible sensor that goes to the
edge? OptiBook 3600? Something else?
Thank you Simon, the --batch-script feature looks very flexible.
It almost does the trick:
scanimage --batch --batch-script (echo) | tesseract - -
Unfortunately, it runs just a little too early. The script executes
just before the temporary image file is renamed. Tesseract
wants to know about
Jeffrey, gscan2pdf is terrific and I expect most users will prefer
the friendly graphical user interface. I would love to compare
notes with you on PDF generation nuances, and also coordinate
with respect to future Tesseract releases.
It's also good have the command line programs connect
together
Thank you, Allan. Tesseract will also accept image data directly
on stdin, so single scan mode should work just fine. I think it is
cleaner to use stdout as opposed to stderr for filenames. I will work
on a patch.
There is one possible alternative. Scanimage could emit image data
to stdout using
When I run scanimage on a Fujitsu S1500, the program is a little
unhappy even after normal operation, note the return code. This
is not great for pipelines. Should I attempt a fix? This is version
1.0.23-3ubuntu3 on the latest Ubuntu release. Sorry, I haven't yet
figured out how to configure a
Implementation was a little intrusive because there is no recovery
from calling freopen() on stdout. This preliminary patch follows
the recommendations of the C FAQ and introduces an explicit
stream variable. I've only done light testing.

Implemented and tested. Please consider for inclusion.

Testing found an error path with a double fclose.
Tiny tweak to make that impossible.

Revised so printing filenames to stdout is optional and defaults to off.
The new option is --batch-print. Please consider applying along with
